SLIDING OR ROLLING GATE.

SPECIFICATION forming part of Letters Patent No. 412,684,dated October 8,1889, i l p g Application nea. January z2, 1889. senti no. 297,124.. (No man.)

` 5 ana, have invented certain new and useful Improvements in Sliding or Rolling Gates;

' and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the f I yIO art to which it appertains to make and use the same.

This invention relates to certain new` and useful improvements in means for operating the opening and closing of sliding or rolling I5 gates; and it consists, substantially, in such features of construction, arrangement, and combinations of parts, as will hereinafter be more particularly described or pointed out.

On the th day of March, 1888, Letters Patent No. 37 9,918 were granted me for certain improvements inthis class of invent-ions, wherein I resort to the use of a rock-shaft extending suitable distances from each side of the gate and having at eachend a beveled gear-wheel 'meshing with corresponding wheels carried by the stirrups, through the medium of which the shaft is rocked or oscillated to open and close the gate. In the patent referred to I have also set forth and claimed other peculiarities 'of construction and arrangement of the several parts resorted to in the carrying out of the invention, as will be seen on inspection of said Letters Patent. The object of the present invention is so tochange'the construction and arrangement of some of the operative mechanism that a much more effective and reliable operation thereof is attained; and a further object of the present invention is to dispense with some of the devices resorted to in the former Letters Patent, therebyr rendering the same much more simpleas well as cheaper to construct or manufacture, lall as will more fully hereinafter appear when taken in connection with the accompanying drawings, wherein-- Figure 1 representsin perspective a view of a sliding or rolling gate having my operative mechanism in connection` therewith. Fig. 2 is a top or plan view thereof, andFig.

` 31s a view in detail of certain parts.

Reference being had to the several part-s by the letters marked thereon, A A represent two vertical posts, which support the gate B by means of grooved pulleys or rollers aa and b h, and C represents the posts againstwhich 5-5 the gate is held when in a closed position. At the base of the innerpostA is a Weatherbox D, in which is contained a spindle c, having rigid therewith on its inner end a beveled gear-wheel c', its other end extending through 6o the box or casing, the said spindle being free to rotate. The beveled gear c of the spindle cmeshes with a similar gear-wheel d, that is rigid with a spindle e, extending through another side of the box D, as shown, the said spindle e being formed at its outer end into a crank e', and free to rotate the same as spindle o.

To the outer end of spindle c is keyed the end of an arm E, the otherV end of which 7o extends up and is pivotally or loosely connected to one end of another arm F, the other end of which is hinged or pivoted to the gate at the upper corner of its inner edge, as shown clearly in the drawings. G G represent two pitmen or connecting rods, which lie in a direction at right angles to the gate, and which are of a length sufficient to permit of the gate being operated to open and close by the wheels of a vehicle 8o without the necessity of the occupant of the vehicle alighting for such purpose. The inner kends of said pitmen or connecting rods G G are loosely connected or attached to the crank e of spindle e, while t-he outer ends of said rods are attached in like manner to cranks g g, formed at the ends of the operating-stirrups HH. These stirrups are located in suitable bearings arranged on opposite sides of the gate in proximityto the outer ends of 9o said connecting-rods G G, and theyv are so.

formed or constructed as that when a vehicle ner be closedautomatically. roo

From the foregoing description itis thoughtI the construction and operation of the several parts of my invention will be fully understood, and it will be seen that the particular construction and arrangement of said parts renders the operation much more simple and eiective than heretofore. It will further be seen that by the employment of but one set of gear-Wheels, instead of two, and the other- Wise simplified mechanism the present invention is much cheaper to construct or manufacture.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a sliding or rolling gate, the combination, With the spindles c and e and their beveled gearing, of the pitinen or connecting rods loosely connected to the crank ot spindle e, and the stirrups to which the outer ends of said pitmen are loosely connected, substantially as described.

2. In a sliding or rolling gate, the combination, with the spindles c and e and their beveled gear-wheels, of the pitmen or connecting rods Gr G, the stirrups H H, the gate B, and the arm E, keyed at one end to the spindle c and at its other end pivotally or loosely connected to arm F, the other end of which latter arm is hinged or connected to the gate, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
